Recycled whirligigs remain fixture in Japanese countryside

A constant fixture of National Geographic Explorer Paul Salopek's journey through rural Japan was the whirligig, or as he called them, "seismic scarecrows." Gardeners he spoke to use these contraptions to scare away crop pests like mice and foxes. Host Carolyn Beeler spoke with Salopek about the whirligigs, rural Japanese architectural aesthetics and how he managed to get aboard a cargo ship to cross to North America.
